-<h1>Chu Shogi (Ancient Japanese Chess)</h1>
-<p>
-Chu Shogi was already known in the year 1250,
-and has been the dominant form of Chess in Japan for many centuries.
-In recent time, after the invention of piece drops, it was overtaken in popularity by modern Shogi.
-It is still widely played in Japan, though.

-<h3>Pawn peculiarities</h3>
-<ul>
-<li>Pawns move <b>and capture</b> straight ahead.</li>
-</ul>
-<h3>General rules</h3>
-<ul>
-<li>The game is won by capturing the opponent's only King.</li>
-<li>Pieces promote at the end of a move into the promotion zone.</li>
-<li>The promotion zone consists of the last four ranks.</li>
-<li>Pieces promote only once.</li>
-<li>Perpetual checking is forbidden, and would be ruled a loss on the 4-fold repeat.</li>
-<li>Other repetitions lose for the side that creates them.</li>
-</ul>
-<h3>Lion moves and Stinging pieces</h3>
-<p>
-Some pieces can make two moves per turn.
-That means they can also capture two pieces per turn,
-one on the square they move to (as normal), and one 'en passant' on the transit square.
-They can also capture on the transit square, and move on to an empty square ('hit and run'),
-or capture and move back to where they came from ('shooting' the piece from a distance, as it were).
-Of course they can also capture a single piece in the normal Chess manner.
-In that case the transit square is immaterial.
-</p>
-<p>
-The Lion can make such double moves as two King steps,
-i.e. in all directions, and arbitrarily changing direction between them.
-The Unicorn and the Eagle can only make double moves in one or two directions respectively.
-They can not arbitrarily change direction, but only reverse it (or not), so they do stay on the ray in that direction.
-But that way they can still make double, hit-and-run, shooting or normal captures.
-All these pieces can also jump over the transit square, i.e. reach the distant two-step destination in a single jump.
-Finally they can also just make a step to an adjacent square, refraining from taking a second step.
-</p>
-<h3>Restrictions on Lion capture</h3>
-<p>
-There are rules to make Lion trading very difficult, in order to keep the Lions in play.
-Basically they specify that two Lions cannot be captured in consecutive half-moves.
-When the first capture is Lion x Lion from a distance, it is forbidden to play it if recapture of the capturing Lion is possible.
-When another piece captures a Lion, it is just the other way around:
-then the 'counterstrike' by a non-Lion against the Lion is forbidden.
-One possibility left open is thus when you capture an adjacent Lion.
-But then you would in general be foolish to allow recapture,
-as you could take the Lion hit-and-run fashion, fleeing to a save square.
-An exception to the rule is when a valuable opponent piece (i.e. not a Pawn or Go Between) forms a 'bridge' between the Lions;
-you may then capture that piece in the first leg of the double-move,
-and then take the opponent Lion with the second leg.
-Then the opponent can recapture, but he will have lost a valuable piece.
-</p>
-<h3>XBoard interface issues</h3>
-<p>
-This game has to be played with the option Show Target Squares on!
-This option will cause marking of the target squares of any piece you select or grab,
-by the engine (with legality testing off) or by XBoard (legality testing on).
-Moving to a square marked in cyan will be interpreted not as the final destination,
-but as the transit square after the first step of a multi-leg move.
-XBoard will then highlight the possible destination squares of the second leg from there.
-Should you want to end on the cyan square, you click it again, (it will be no longer marked in cyan),
-and XBoard will terminate the move after the first leg.
-You can also move back to the starting square, to 'shoot' the opponent piece from nearby.
-</p>
-<p>
-With Detour Underpromotion on, XBoard will assume by default that every piece that enters the zone promotes.
-Should you want to defer in this mode, you should use a click-click move,
-and when you make the click on the promotion square,
-move the mouse down before releasing the button.
-If you move enough the piece on the promotion square will change back to the unpromoted form,
-and then you can release.
-With Detour Underpromotion off, you will automatically get a promotion popup that asks whether you want to promote or defer.
-</p>
-<h3>Differences with FIDE</h3>
-<p>
-Except that there are also Kings, Queens, Rooks and Bishops, not much is the same.
-</p>
-<h3>Strategy issues</h3>
-<p>
-Piece with no sliding forward moves are hard to promote,
-but promotion of forward sliders is practically unavoidable.
-</p>
-<p>
-You can have two Kings by promoting the Elephant, in which case the opponent would have to capture both in order to win.

+ <h3>Pawn peculiarities</h3>
+
+ <ul>
+ <li>Pawns move <b>and capture</b> straight ahead.</li>
+ </ul>
+
+ <h3>General rules</h3>
+
+ <ul>
+ <li>The game is won by capturing the opponent's only King.</li>
+
+ <li>Pieces promote at the end of a move into the promotion
+ zone.</li>
+
+ <li>The promotion zone consists of the last four ranks.</li>
+
+ <li>Pieces promote only once.</li>
+
+ <li>Perpetual checking is forbidden, and would be ruled a loss
+ on the 4-fold repeat.</li>
+
+ <li>Other repetitions lose for the side that creates them.</li>
+ </ul>
+
+ <h3>Lion moves and Stinging pieces</h3>
+
+ <p>Some pieces can make two moves per turn. That means they can
+ also capture two pieces per turn, one on the square they move to
+ (as normal), and one 'en passant' on the transit square. They can
+ also capture on the transit square, and move on to an empty
+ square ('hit and run'), or capture and move back to where they
+ came from ('shooting' the piece from a distance, as it were). Of
+ course they can also capture a single piece in the normal Chess
+ manner. In that case the transit square is immaterial.</p>
+
+ <p>The Lion can make such double moves as two King steps, i.e. in
+ all directions, and arbitrarily changing direction between them.
+ The Unicorn and the Eagle can only make double moves in one or
+ two directions respectively. They can not arbitrarily change
+ direction, but only reverse it (or not), so they do stay on the
+ ray in that direction. But that way they can still make double,
+ hit-and-run, shooting or normal captures. All these pieces can
+ also jump over the transit square, i.e. reach the distant
+ two-step destination in a single jump. Finally they can also just
+ make a step to an adjacent square, refraining from taking a
+ second step.</p>
+
+ <h3>Restrictions on Lion capture</h3>
+
+ <p>There are rules to make Lion trading very difficult, in order
+ to keep the Lions in play. Basically they specify that two Lions
+ cannot be captured in consecutive half-moves. When the first
+ capture is Lion x Lion from a distance, it is forbidden to play
+ it if recapture of the capturing Lion is possible. When another
+ piece captures a Lion, it is just the other way around: then the
+ 'counterstrike' by a non-Lion against the Lion is forbidden. One
+ possibility left open is thus when you capture an adjacent Lion.
+ But then you would in general be foolish to allow recapture, as
+ you could take the Lion hit-and-run fashion, fleeing to a save
+ square. An exception to the rule is when a valuable opponent
+ piece (i.e. not a Pawn or Go Between) forms a 'bridge' between
+ the Lions; you may then capture that piece in the first leg of
+ the double-move, and then take the opponent Lion with the second
+ leg. Then the opponent can recapture, but he will have lost a
+ valuable piece.</p>
+
+ <h3>XBoard interface issues</h3>
+
+ <p>This game has to be played with the option Show Target Squares
+ on! This option will cause marking of the target squares of any
+ piece you select or grab, by the engine (with legality testing
+ off) or by XBoard (legality testing on). Moving to a square
+ marked in cyan will be interpreted not as the final destination,
+ but as the transit square after the first step of a multi-leg
+ move. XBoard will then highlight the possible destination squares
+ of the second leg from there. Should you want to end on the cyan
+ square, you click it again, (it will be no longer marked in
+ cyan), and XBoard will terminate the move after the first leg.
+ You can also move back to the starting square, to 'shoot' the
+ opponent piece from nearby.</p>
+
+ <p>With Detour Underpromotion on, XBoard will assume by default
+ that every piece that enters the zone promotes. Should you want
+ to defer in this mode, you should use a click-click move, and
+ when you make the click on the promotion square, move the mouse
+ down before releasing the button. If you move enough the piece on
+ the promotion square will change back to the unpromoted form, and
+ then you can release. With Detour Underpromotion off, you will
+ automatically get a promotion popup that asks whether you want to
+ promote or defer.</p>
+
+ <h3>Differences with FIDE</h3>
+
+ <p>Except that there are also Kings, Queens, Rooks and Bishops,
+ not much is the same.</p>
+
+ <h3>Strategy issues</h3>
+
+ <p>Piece with no sliding forward moves are hard to promote, but
+ promotion of forward sliders is practically unavoidable.</p>
+
+ <p>You can have two Kings by promoting the Elephant, in which
+ case the opponent would have to capture both in order to win.</p>
